at firehouse subs a gluten free roll costs +$1.50, they don’t even prepare it separately from normal bread and use all the same tools for it (except for not cutting it) so it’s not actually properly gluten-free, it’s almost certainly contaminated with gluten.

jersey mikes also charges +$1.50 (medium) to +$3.00 (large) to get gluten-free bread, but at least they have to go through a whole ritual to prepare it where they use COMPLETELY different tools and gloves and stuff, and it is generally actually non-contaminated unless, you specify that it’s not for allergies.

source: i worked at both firehouse subs and jersey mikes before, i fucking hated when people ordered gluten-free at jersey mikes but i always did it as required obviously. i didn’t actually ever charge extra to people who were getting gluten free because i didn’t know that was an option on the cash register at first lol, but even after i learned i just forgot / didn’t care enough to do it. some people were really grateful and thanked me after seeing me go through an entire process to make sure the gluten-free sub had no gluten on it
